Build 1 cryptocurrency API method that returns some simple chart data

I need 1 simple cryptocurrency API method to be developed.

-The API can be built in any programming language

-The API should be uploaded to some VPS and it should be made available to use

-The source code should also be delivered

-This project is urgent. It needs to be done in the next 24 hours. It is simple. It should be too hard.

The API method should return the changes in following cryptocurrency price for the last 24 hours : BTC, ETH, BCH, LTC. It should look like this: http://<some-address>/api/get-chart-data?currency=<currency>

where <currency> is target currency in which price is presented.

<currency> can have 2 values: USD and EUR.

And the response from the API should look like this:


targetCurrency: <targetCurrency>,

changes: {

'BTC': <24 hour BTC price change percentage>,

'ETH': <24 hour ETH price change percentage>,

'LTC': <24 hour LTC price change percentage>,

'BCH': <24 hour BTh price change percentage>



The changes should be in percentage. The targetCurrency value is just the value that was passed to the API.

So, here's an example:

The API is called like this: GET http://<address>/api/get-chart-data?currency=USD

The response should look like this:


targetCurrency: 'USD',

changes: {

'BTC': 1.4,

'ETH': 4.0,

'LTC': 5.0,

'BCH': 6.2



To get a better understanding of what I'm looking for you can take a look at [login to view URL] and look at 24h change column. I need that just for thease 4 cryptocurrencies and just for USD and EUR as matching currency.

So, to sum it up the deliverables are:

-The API method uploaded to some VPS online and accessible trough the internet (should be available for a minimum of 30 days)

-The source code of the API

Skills: Python, Java, Javascript, Blockchain, Ethereum
